As had been described in the past that usually ROM used for storing firmware. On the computer, are often found to store the BIOS. When a computer is turned on, the BIOS can be directly executed quickly, without having to wait for powering the tool storage media in advance as is common in storage devices other than ROM.
Usually, on the other storage media, if executed to read the contents or knowledge, storage media must be turned on first before it is read, which of work requires some time. Things like this do not happen in the ROM.
On the computer (PC) modern BIOS is stored in ROM chips that can be electrically re-writeable known as Flash ROM. That is why the term is more popular than the ROM BIOS.
